Title: Improvements relating to flushing cisterns for water closets
IPC: E03D1/07
Filed: 1946-07-15
Abstract: 597,906. Water-waste preventers. FREEMAN, F. July 15, 1946, No. 17965/45. [Class 26] In a flushing cistern of the externallyactuated siphon type, the siphon comprises a plurality of flexible curved pipes o extending from the flush pipe q upwards to rigid links m connecting them to a spring- (i) loaded lever k, whereby they are held normally at one point above the highest water level in the cistern with their free ends s submerged, and said lever being operable against its control spring to depress the pipes o to become completely submerged and so initiate siphonic action. An open cup-shaped member u depending from the free ends s of the pipes o is said to render the termination of the siphonic action more positive in that when the water level falls to that of small holes that are formed in the pipes slightly above the edge of the cup u, siphoning ceases, water pressure on the cup due to water motion ceases and the flexed pipes lift it momentarily clear of the water level so fully breaking the siphon. The cistern is provided with a well t into which the cup u and the free ends s of the siphon are depressed on flushing. The lever k may be actuated mechanically by the arm g, or electromagnetically. An electric lamp e may be provided to prevent freezing of the water in cold weather.

Title: Angle modulated carrier wave detector
IPC: H03D3/32
Filed: 1945-07-13
Abstract: 605,878. Frequency modulation; circuits for cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 13, 1945, No. 17986. Convention date, July 14, 1944. Addition to 605,715. [Classes 40 (v) and 40 (vi)] [Also in Group XL (a)] A detector for angle-modulated carrier waves comprises a discriminator for deriving a pair of high-frequency voltages whose relative magnitudes vary in accordance with the frequency of the applied wave, a cathode-ray tube having an output electrode with at least two areas of different secondary electron. emissivity, and deflector elements to sweep the primary electron beam over the-two areas in response to the high-frequency voltages to vary the output electrode current. The discriminator of a frequency-modulated superheterodyne receiver, Fig. 1, consists of a primary tuned circuit 13 coupled to two off-tune circuits 15, 16 which are connected to the deflection plates 5, 6 of a cathode-ray tube 1. The cathode-ray tube has a focussing electrode 4 and two pairs of deflection plates 5, 5<1>, 6, 6<1>, one of each pair being earthed. The primary electron beam 3 is swept in an elliptical path over the circular target T in response to the relative amplitude variations in the H.F. voltages appearing at the deflection plates. The target T has four equal sectors of different secondary electron emissivity, the diametrically -opposed sectors is maintained at a lower positive potential than the collector 'electrode E, which is constructed so as to permit the passage of the primary beam 3 in which it is placed. As the frequency of the received wave varies, the pattern traced on the target T by the primary electron beam 3 changes, thus varying the width and recurrence frequency of the output pulses which appear across resistance R. Since the shape of the pattern traced on target T by beam 3 is independent of the amplitude of the received wave, and the output voltage of target T does not depend on the size of the trace, the signal appearing across integrating condenser 11 is independent of amplitude variations in the received wave. In a modification, Fig. 5, the target T has a central hole 30 slightly larger in diameter than the electron beam, so that no output appears across resistance R when no signal is present, thus reducing noise effects. U.S.A. Specification 2,344,679 is referred to.

Title: Slide projector
IPC: G03B23/04
Filed: 1971-05-28
Abstract: 1355532 Optical projection apparatus S BESANCENOT 28 May 1971 [5 June 1970] 18039/71 Heading G2J A slide projector able to feed slides from a stack in a channel to the projection gate and back has a resiliently biased deflector member 120 in the channel which is narrower than the channel. As shown the slides are placed in a stack A between thrust members 106, 107 and stops 118, 119. A slide pusher member 116 has a pivotable arm 122 and moves in association with return pusher 117 to move slides to and from the gate 113. Pins 129, 130 are moved to the left (as shown) if the slides are to feed from the stack A via the gate 113 to between the stops 118, 119 and thrust members 109, 110; the pins are moved to the right if reverse movement is desired. Pins 130, 129 bias the arm 122 to right and left respectively. Thus as the member 116 moves up (as viewed) the arm 122 pushes the end slide of stack A into the gate. When the member 116 descends the pusher 117 and deflector 120 direct the slide between the stops 118, 119 and members 109, 110. To return this slide via the gate 113 to the stack A pins 129, 130 are moved to the right, this also rotates the deflector member 120 through about 90 degrees so that it is biased to direct slides returning from the gate 113 to stack A.

Title: An improved coin freed machine for the sale of sweetmeats, sandwiches, newspapers and the like
IPC: G07F11/52
Filed: 1932-06-27
Abstract: 398,975. Coin-freed article-delivery apparatus. MORNAND, G., 179, Calea Dorobantilor, and ALBU, N. N., 16, Strada Lanariei, both in Bucharest. June 27, 1932, No. 18157. Convention date, March 4. [Class 27.] Articles stored in rotary drum.-In coin-freed vending-apparatus, the articles are stored between radial members 11 on a drum 10, Fig. 2, which is partially set in motion by an inserted coin, the coin subsequently acting by weight to free a release mechanism enabling the drum to be rotated by hand through an opening which also serves for the extraction of the goods. The drum is journalled on a hollow axle 7 secured within an upper cylindrical part 6 of the casing 5, and the front and top of the outer casing are open at the part corresponding with the top sector of the drum to enable the latter to be rotated in the direction of the arrow and the articles extracted ; rotation in the opposite direction is prevented by a detent 43 which engage the radial divisions. Coin action, weight.-A coin inserted through the slot 16 passes between a plate 15, Figs. 4 and 11, and the back 17 of the compartment 6 and is guided by a projection 18 and a ledge 32 on to a projection 19 on a pivoted member 20 weighted at 26, after which it falls into a receptacle 35. The member 20 engages any one of a set of equidistant studs 23 on the back of the drum 10, corresponding in number to the compartments, and is disengaged therefrom by the coin striking the projection 19, reengagement with the same stud being prevented by a pivoted tip 25. The drum may now be rotated through one division and an article extracted, further rotation being prevented by the engagement of the member 20 with the next stud 23. Fraud preventing; testing coins.-Access to the member 20 by a piece of wire &c. is prevented by the members 18, 32, and a rib 46 on the plate 15. If the coin is of insufficient thickness, it passes between the ledge 32 and the back of the compartment 6 ; if of insufficient diameter, it passes freely between the projection 19 and the side of the casing 5 ; if of insufficient weight it does not deflect the member 20, but is removed therefrom by the insertion of the next coin ; and if of magnetic material, it adheres to the magnet 36. Returning coins.-A thin coin not retained by the ledge 32 falls into an open compartment 31, from which it may be removed. If a correct coin is prevented from actuating the machine by a magnetic disc adhering to the magnet, or other foreign bodies which may have been inserted through the slot, it may be recovered via the compartment 31 by pressing the button 37, which moves back the plate 15 against the action of a spring 41. Coin-slit closing-devices.-A pivoted flap is adapted to be moved up beneath the coin slot 16 by means of a stud 27 on the drum when the last compartment has been emptied.

Abstract: 635,151. Conduits. DIMMENDAAL, J. J. July 9, 1947, No. 18184 and 18185. Convention dates, March 10, 1943. [Class 33] [Also in Groups XXVIII and XXXVI] In a process for the manufacture of conduits from wire-armoured asbestos or fibrous-cement, the conduit is made from hardened prefabricated slabs first formed to the desired dimensions, after which the armouring 1, Fig. 3, is laid bare at the edges, the projecting wires of two adjacent slabs being then connected, e.g., by welding or twisting as at 14, Fig. 6, and the corner seams then filled with mortar. A bitumen cord 2 or 20, or other packing cord, is laid in the space between the inner edges of the slab and the wires prior to joining them. A slab 5; Fig. 4, may have fibrous material removed on opposite sides to form grooves 6, where the exposed wires may be bent as required, the exposed ends of the wires from the slab 5 and the base slab 7 being twisted together and the seams so formed packed as above. By having transverse joints 4 formed as above any length of conduit can be obtained. Slabs may be joined by fitting U-shaped guides 15, 16, Fig. 6, round their edges, the outside legs of said guides enabling sliding angled borders 17, e.g., of sheet iron, with edges bent to form channels 19, 18 to be placed over said guides. Two adjacent borders may be so shaped as to be telescopic. The bent edges of the borders may have recesses so that they can be placed around an edge by first bringing the recesses in front of the projecting guides and then sliding each border over a predetermined distance. The Specification as open to inspection under Sect. 91 comprises also (1) the use of cement in place of mortar for the joints, and (2) the omission of the packing cord. This subject-matter does not appear in the Specification as accepted.

Wire strainers. -In a hand-operated machine for wiring boxes, bales &c. of the kind in which the box &c. is placed on the top of the machine and in which the twisting pinion is rotated through an even number of turns, plus a fraction of a turn, and is then rotated in the reverse direction through the fraction of a turn to relieve the strain of the wires in the pinion slot and to facilitate removal of the package, the reverse rotation is effected, on release of the actuating lever or hand wheel, by a spring-energized pivoted arm engaging a co-operating member part in the driving shaft or on a shaft geared therewith. The free end of the wire is held between the fixed and spring- pressed jaws i, i<1> and the wire is passed under a spring-pressed bolt k, then through the pinion c and under the secondary holding bolt l and, after passing round the bale placed on the top of the machine, is again placed under the bolts and through the pinion and then under a pair of holding down bars j, j<1> and the other end is finally secured in the spring-closed jaws m of a tensioning slide. This slide is normally pressed forward by a spring n<1> to open its jaws against a wedge and is withdrawn by a pedal through a stranded cable or chain m<1> so as to close the jaws on the wire, which is then drawn back to tension it round the bale. The pinion c is now operated by a hand-driven shaft a geared thereto through an intermediate pinion d<1> loosely mounted on a cam shaft d, which is driven from the shaft a through gears d<2>, e<1>, a<3>. The shaft a carries a cam f which in the initial part of its rotation forces down a lever g against the pressure of its spring g<1>, and when a stop a<0> on the hand-wheel a<1> engages a spring-pressed latch h so as to stop its rotation the lever engages a recess in the cam, and when the hand-wheel is released the spring g rotates the shaft in the reverse direction until it is stopped by an adjustable stop f<1> on the cam engaging a shoulder g<2> in the lever. The holding-down bolts are released by cams a and are held in retracted position by spring latches k<2>, l<2>. After twisting, the ends of the wire are severed by cutters q. The slotted pinion may be geared to a parallel intermediate shaft bevel-geared to a transverse shaft actuated through a ratchet lever which may be given one, two, or more throws.
